Spring Security 6 & JWT Authentication · Lesson

In-Memory User Authentication

Implement basic authentication using in-memory user details, configuring usernames, passwords, and roles directly.

Welcome to In-Memory Auth

The fastest way to add real users: in-memory authentication. You define accounts straight in code — perfect for tests and tiny apps.
